1. Data We Collect

We collect the following personal data:

2. How We Use Your Data

3. Your Deck Content

Analysing a deck requires processing what is on it. This section states exactly what that involves and what it does not.

We commit that:

To be equally clear about what does happen:

4. Third-Party Services

We use the following third-party services to operate FactRefresh:

5. Analysis Packs

An analysis pack is the vocabulary FactRefresh uses to research your deck: the kinds of development it looks for and the search phrasings it uses. You can choose one of our built-in packs, edit a copy, or generate one from a description you write of your field.

A pack is built from your description, never from your deck. Generation reads the text you type into the description box and nothing else, so a pack contains general vocabulary for a field rather than anything specific to your slides.

Packs you create are private to your account by default. If you tick "Allow this pack to be used to improve FactRefresh", you are giving us permission to view that pack and the description it was generated from, and to use them to improve our built-in packs. That permission covers the pack only. It does not extend to your decks, and ticking it changes nothing in section 3. You can withdraw it at any time in the pack's settings, and we will stop using it from that point.

6. File Retention

The file you upload is not retained. It is read into memory, the text is extracted, and the original file is not written to storage.

The extracted text is kept, because the review screen displays it, and that is what you come back to. It lives for as long as the project does. Deleting a project deletes its slides, its suggestions and its cited sources immediately, and deleting your account deletes all of them.

You can delete your account yourself, from the billing page. It is immediate and permanent. There is no grace period and no backup copy of your projects to restore from. Cancel your subscription first if you have one, or Stripe will keep billing a customer who no longer has an account.

7. Cookies

We use session cookies for authentication. We do not use third-party tracking cookies or analytics scripts.

8. Your Rights (GDPR)

If you are in the EU/EEA, you have the right to:

Deletion and export you can do yourself: deletion from the billing page, and export from any project's review screen. For the rest, contact us at the email address listed below.

9. Data Security

Traffic between your browser and FactRefresh is encrypted in transit (TLS). Files you upload are encrypted at rest with AES-256 by our storage provider — though, as section 6 says, we do not keep them. Passwords are hashed with bcrypt. API keys and secrets are held in environment variables, never in source code.

10. Changes

We may update this policy from time to time. Changes take effect upon posting. Continued use of the Service constitutes acceptance.
